Application filed July 12,

To all 10710212 it may "concern:

Be it known that I, ELBninon R. I'IonMEs, a citizen of the UnitedStates, residing at Worcester, in the county of lNorcester and State ofMassachusetts, haveinvented anew and useful Narroware Loom, of which thefollowing is a specification.

This invention relates to a narrow ware loom and particularly toimproved devices for supporting the rolls of ribbon or other materialwoven 'by the loom. It has been customary to wind-these rolls uponshaftsof considerable lengthan'd it w'asnec'ess'ary to take out the entireshaft to remove any one of the rolls mounted thereon.

It is the general object of my invention to provide a construction bywhich the rolls are independently mounted, thus permitting convenientremoval or replacement of any desired roll.

A. further object of my invention is to'provide improved means forholding aroll, permit-ting also very easy removal of the roll from itsroll holder.

lVith these general objects'in view, important features of my inventionrelate to novel means for securing and operating the roll holdingfingers and to a novel device for axially positioningthe roll holdingsupport in the loom.

My invention further relates to arrange ments and combinations of partswhich will be hereinafter described and moreparticuiarly pointed out inthe appended claims.

A preferred form of my invention is shown in the drawingsin' Which- Fig.1 is a partial front elevationof the takeup mechanism of a narrow wareloom;

Fig. 2 is'a sectional side elevation, taken along the line 2+2 in Fig.1;

Fig. 3 is an enlarged front elevation of.

one o f the roll holders;

Fig. a is a side elevation thereof, taken in the direction of the arrow4in Fig. 3;

Fig. 5 is a plan view of one of the blanks from which the positioningdevices are formed;

Fig. 6 is a sectional elevation of one of the positioning devices;

Fig. 7 is a sectional elevation of a modified form of'roll holder, takenalong the line T? in Fig. 8; and 1 larger than the shaft 17.

1921. Serial No. 484,196.

Fig. 8 is a left hand side elevation ofthe parts shown in Fig. 7.

Referring to the drawings, I have-shown a portion of a loom frame 10 inwhic'his rotatably mounted the usual tak'eup roll 11.

'lidler pulleys 12 are mounted on swinging arms 13 and the ribbonorother material It passes under the roll 11 and over-the roll 12- fromwhich it is led downward-to the roll holder.

Each roll holder comprises a hub 14' (Fig. mounted on a stud 15secured'in theupper end of an arm 16 loosely pivoted upon a fixed shaft17. The axialpos'ition of the roll holder relative to the takeup roll 11'and shaft 17 requiresoccasional adjustment and for-this purpose thearms 16 are positioned lengthwise on the shaft 17 by theadjustableholding devices 18 shown in detail in Figs. 5 and 6.

Each holding device 18' comprises a single piece of sheet material,preferably spring steel, first blanked out as shown in Fig. 5 andprovided with two openings 19 slightly The blanks are then bent to theform shown in Fig. 6 and are slipped over the shaft '17 with one of thearms 16 held between thetwo parts of each holding device. lVhen thesides of'the device 18 are pressed together to substantially parallelposition the device and arm maybe freely moved longitudinally oftheshaft 17, but when released the sides swing apart and grip the shaft. Ihave thus provided an ex:- tremely convenient means for axiallyadjusting and holding the arms "16 on the shaft 17.

The hubs 14 are each provided with a circumferential groove 20 and witha plurality of transverse notches 21 intersecting the groove 20. Theroll holding members comprise a plurality of fingers 22, each preferablyformed of a single piece of sheet A collar 26 is slidably mounted on thestud and when moved to the left in Fig. 3 moves the fingers from thedotted line to the full line position in said figure. hen in the latterposition the fingers are well adapted to form the foundation for a rollof ribbon, tape or other narrow material which may be wound directlyupon the fingers as indicated in Fig. 3 or may, if preferred, be woundupon a tube as indicated in Fig. 7 When the roll is completed, thecollar 26 may be pushed inward, allowing the fingers 22 to collapse, andfreeing the roll for easy removal.

The construction shown in Figs. 7 and 8 is particularly adapted forsupporting rolls wound upon tubes and comprises a roller 30 rotatableupon a stud 31 and having a circumferential groove 32 near one endthereof. Transverse slots 33 and 34: are formed atone point in thecircumference and a resilient metal finger 35 is held from displacementin the slots by a binder 36 as previously described. The middle portionof the finger 35 rests upon a projection 37 between the slots 33 and 34and the outer end of the finger 35 is preferably provided I with a sp'ur38 adapted to extend into the tube 39 and prevent relative rotationthereof. When the material and tube are to be removed, the projectingouter end of the finger 35 may be depressed to withdraw the spur 38 fromthe tube. This construction is desirable when a tube is used as afoundation for the roll but does not permit as easy removal of the rollwhen no tube is used.

The roll holder in each case is preferably rotated by an elasticfriction band 40. The

takeup roll 11 and the hub 1e are so proportioned that the roll willbe'rotated at sufficient speed to wind up the material at the smallestdiameter of the roll. As the roll increases in size, the elastic band 10slips throu h the groove 20, thus permitting lost motion between theroll and band and turning the roll only fast enough to wind up theribbon delivered thereto.

A weighted arm 41 preferably extends rearwardly from each arm or support16 and normally holds the parts in the position shown in Figs. 1 and 2but permits any roll to be swung forward for inspection or removal.

Having thus described my invention, the use and advantages thereof willbe readily apparent and it will also be seen that changes andmodifications can be made therein by those skilled in the art within thespirit and scope of my invention as set forth in the claims. Therefore,I do not. wish to be otherwise limited to the details herein disclosedbut What I claim is 1. In a narrow ware loom, a fixed shaft, a pluralityof arms mounted to swing freely on said shaft and longitudinallyadjustable thereon, means tohold each arm in adjusted longitudinalposition, and a roll holder rotatably mounted on each arm.

2. In a narrow ware loom, a'fixed shaft, a plurality of arms mounted toswing freely on said shaft and longitudinally adjustable tliereon, meansto hold each arm in adjusted longitudinal position, a roll holderrotatably mounted on each arm, and means to rotate said roll holders.

'3. In a narrow ware loom, a fixedshaft, a plurality of arms mounted toswing freely on said shaft and longitudinally adjustable thereon, meansto hold each arm in adjusted longitudinal position, a roll holderrotatably mounted on each arm, and means yieldingly retaining said armsin normal position.

6. In a narrow ware loom, a roll holder comprising a hub having acircumferential groove and an axially extended notch, a holding fingerseated in said notch and extending across said groove, and a binder insaid groove preventing displacement. of said finger. e

7. In a narrow ware loom, a take-up roll, a plurality of cloth rollslocated adjacent the take-up roll and having their axes normally insubstantial alignment, and individual mountings for said cloth rollspermitting each roll to be moved independently out of alignment with theother rolls.

8. In a narrow ware loom, in combination, a tube, a driven roll on whichsaid tube is supported, said roll having an axially extended groove anda circumferential recess, a tube driving member mounted in said grooveand yieldingly engaging said tube, and holding means for said memberpositioned in said circumferential recess.

9. In a narrow ware loom, in combination, a tube, a drven roll on whichsaid tube is supported, said roll having an axially extending recesswith a raised intermediate portion, and a resilient arm secured at oneend in said recess and also engaging said intermediate portion, the freeend of said arm yieldingly engaging and driving said tube.

10. In a narrow Ware loom, in combina tion, a tube, a driven roll onwhich said tube is supported, said roll having an axially extendingrecess with a raised intermediate portion and a resilient arm secured atone end in said recess and having its middle portion engaged by saidraised portion, the free end of said arm having a 10 spur yieldinglyengaging said tube to drive the same.
